TCSN Merak HESS Series – Redefining All‑Scenario Smart Energy Storage

Against the backdrop of global energy transition and grid volatility, the need for energy autonomy among households and commercial users has evolved from simple "backup" to proactive "intelligent management." The Merak HESS Series High‑frequency Off‑grid Stackable All‑in‑One from TCSN Power is engineered precisely for this new reality. More than just a battery, it is a complete all‑scenario smart storage system that integrates PV input, grid interaction, and intelligent dispatching – putting every kilowatt‑hour to work for your low‑carbon lifestyle and business resilience.

Built tough for demanding environments. The Merak HESS Series utilizes long‑life Lithium Iron Phosphate (LFP) cells, delivering an impressive 8,000 cycles at 80% DOD – equivalent to over 20 years of reliable service with daily one‑charge‑one‑discharge operation. The system supports a wide discharge temperature range from -20°C to 55°C and is available with an IP65‑rated enclosure, ensuring consistent performance whether in freezing winters or scorching deserts. With stackable battery modules from B5 (5.12kWh) to B16 (16.08kWh) and high current capabilities of 150A to 300A, the system easily handles high‑power appliances and short‑term peak loads.

Modular stacking, plug‑and‑play, and effortless expansion. Say goodbye to complex cabinets and cumbersome wiring. The Merak HESS features a visual stackable design, with each module weighing as little as 46kg for easy two‑person assembly. Battery modules are electrically connected via plug‑in terminals and support parallel multi‑unit expansion, scaling flexibly from 5kWh to over 100kWh – ideal for daily home backup, off‑grid villa autonomy, or commercial peak‑shaving and arbitrage. The built‑in intelligent parallel management means adding new modules requires no complex debugging; true "building‑block" scalability.

Smart brain for total energy control. The integrated hybrid inverter and dual‑communication module (WiFi/GPRS) connect the system to a cloud‑based monitoring platform in real time. Through the mobile App or web portal, you can check PV generation, battery status, and load consumption anytime, anywhere. Two preset operating modes – "Utility‑first" and "Battery‑first" – let you prioritise solar and battery power during peak tariff hours and automatically switch to grid supply when rates are low, maximising savings. The system also supports seamless on‑grid/off‑grid switching, with backup activation in under 10ms during grid outages to protect sensitive equipment and critical loads.

Safety and aesthetics in perfect harmony. Every cell is protected by rigorous voltage, temperature, and short‑circuit safeguards, while the BMS (Battery Management System) continuously monitors each string to ensure rapid response to over‑charge, over‑discharge, or over‑current conditions. The sleek, integrated industrial design is complemented by an intuitive LED status panel (or optional touchscreen display) for at‑a‑glance system status. With an IP21 standard rating (upgradable to IP65) and a fan‑less natural cooling architecture, the unit operates silently and blends seamlessly into home or equipment room settings.

One system, all scenarios – from home to business. Whether used as a home emergency backup to keep lights and internet running during blackouts, as an off‑grid PV storage solution for remote farms or telecom base stations, or for C&I peak‑shaving and demand‑charge reduction – the Merak HESS adapts to every need with a single standardised platform. Its high‑frequency topology further delivers system efficiency exceeding 97%, minimising energy losses throughout the conversion chain.
